Bummed

I have several pairs of the Freeflex pants and love them, so I was excited to try the shorts out for summer. I ordered a medium and a large bc I’m often in between sizes. The medium is so tight, I can barely get it over my butt, is a little snug in the waist and the crotch is extremely tight and uncomfortable. The large is so big that even when I tighten the drawstrings, they immediately fall down. Not sure why there is such a massive discrepancy in the fit of these two but I am disappointed and will be returning both. The waistband is also very stiff and has very little give.
